Just when sleep starts feeling like it’s finding a rhythm, six months can throw it sideways again. The good news: this one is usually shorter and easier to explain than the 4-month shift.
What’s usually driving it
The 6-month regression is typically tied to one or more of: rolling (practicing a new physical skill even in sleep), teething discomfort, or a nap transition as the day’s rhythm starts to shift. Unlike the 4-month change, this isn’t a permanent restructuring of sleep architecture — it’s usually a temporary disruption layered on top of a skill or discomfort.
How long it tends to last
Most versions of the 6-month regression resolve within two to three weeks. If it’s dragging on much longer than that, it’s worth checking in with your pediatrician to rule out other causes — but the short timeline is the norm, not the exception.
Ask the same two questions every time: has this lasted more than two weeks, and is there an obvious developmental leap or new skill in progress (rolling, a new tooth)? If yes to both, ride it out with consistency rather than overhauling the whole routine.
What helps
- Give extra rolling practice during awake time so there’s less urge to practice it at 2 a.m.
- Check for teething signs — drooling, chewing on hands, swollen gums — and talk to your pediatrician about appropriate comfort options if needed.
- Keep the wind-down routine identical even if the night itself is rougher. Consistency in the parts you control balances out the parts you don’t.
- Resist the urge to introduce a brand-new sleep strategy mid-regression. It’s hard to tell whether a change worked or the regression simply ended on its own, and you may end up attached to a habit you didn’t actually need.
